When every option on the table is a variation of one route or waits on the same sign-in, approval, person or dependency, list the options that frame already gives, then map working mechanisms from five or more distant domains onto the problem and report the ones the first list lacked, each with where it breaks. Use when work is stuck inside one frame, when the user asks how another field or industry would solve it, or asks for an analogy that actually transfers. Not for re-reading a decision at…

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'crossthink' ] || [ -L ~/.agents/skills/'crossthink' ]; then echo 'A skill folder named crossthink already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/LilMGenius/paperthin' "$d" && git -C "$d" checkout --quiet '61143228dae8549f4ebc3e9f3d8d65cb4bbe7764' -- 'skills/depth/crossthink' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/depth/crossthink' ~/.agents/skills/'crossthink' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'crossthink' ~/.claude/skills/'crossthink' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
